How to encrypt in a pgcrypto compatible way in python

Question

For a project I am working on I would like to use a pgcrypto compatible encryption in python. And specific the public key encryption part.

The problem I have is that most (all) of the implementations make use of subprocess like approaches to fork gpg, as I have to encrypt a lot of data (50.000+ entries per session) this approach will not work for me.

Can someone give me some pointers how that this could be achieved?

Depends what type of encryption you use. First, are you using raw encryption funtions like "encrypt(data bytea, key bytea, type text) returns bytea" or PGP stuff like "pgp_pub_encrypt(data text, key bytea [, options text ]) returns bytea"? — Stefan Rasmusson

Both options are open and I have no strong favour for one or the other — Wouter

Have a look at PyCrypto, it doesn't seem to use forking. pgcrypto can be configured to fit most crypto configurations.

Thank you, I guess that my question was nog clear enough. I am looking for a more detailed answer from someone that has experience with a simular problem. I know PyCrypto could be used, but I have no clear idea on how to use it correctly.
